Herein, we report a convenient solvent-controlled regioselective esterification to access two types of carboxylate esters without any additive or non-green activation strategy. In this transformation, 2-methyleneaziridines served as an ester reagent, providing two alternative electrophilic carbon centers. Notably, this protocol is suitable for some structure-complicated clinical molecules with a carboxylic acid group, presenting remarkable application potential.
在此,我们报告了一种方便的溶剂控制区域选择性酯化方法,无需任何添加剂或非绿色活化策略即可获得两种类型的羧酸酯。在这种转化中,2-亚甲基氮丙啶作为酯试剂,提供了两个替代的亲电碳中心。值得注意的是,该方案适用于具有羧酸基团的一些结构复杂的临床分子,具有显著的应用潜力。
